The CAS Registry Mumber 8038-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,3 and 8 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 8038-37: (6*8)+(5*0)+(4*3)+(3*8)+(2*3)+(1*7)=97 97 % 10 = 7 So 8038-37-7 is a valid CAS Registry Number.
